| Abstract: | This paper presents the KL transformation method for the regional geophysical exploration dataprocessing,and the method can reduce the ransom noise to the inferior limit by KL transformation,extract char-acterise and reconstruct data.The results of synthetic and practical data processing indicate that the digital filter-ing effect is very good and the signal-noise radio is fully increased. |
